In the SM the conservation of discrete symmetry of quark flavors is a key is- sue for the model, only through charged EW interactions flavor changing is permitted. Nevertheless, the current data of experiments have showed some B semileptonic decays non-universality for lepton families. This difference can not be accomplished by electroweak SM processes, since they are exaclty the same for the...
We analyze the production of a light charged Higgs boson at the Large Hadron Collider (LHC) via the quark-fusion mechanism cb¯→H- considering the decay channel H-→τν¯τ in the final state. We study this process in the framework of the two-Higgs-doublet model type III (2HDM-III) which assumes a four-zero texture in the Yukawa matrices and a general Higgs potential, wherein the two Higgs doublets...

Many extensions of the Standard Model introduce additional Higgs-like bosons as well as exotic decays of the 125 GeV Higgs boson. The current status of searches by ATLAS and CMS for doubly-charged Higgs bosons, additional neutral Higgs bosons and non-SM decays of the 125 GeV scalar particle, based on the LHC Run 2 dataset, are presented.

In this work, we analyze a light charged Higgs boson in the 2-Higgs Doublet Model (2HDM) Type-I, when its mass satisfies the condition $M_{H^{\pm}} < M_{t}+M_{b}$ and the parameter space is consistent with theoretical requirements of self-consistency as well as the latest experimental constraints from Large Hadron Collider (LHC) and other data.
